Installation steps:

1. Install the card on the  Razer Core X  (by following the basic instructions in the manual), the RTX 3070 TI needs all the pin connectors.
2. Connect the  TB3 cable to the only TB3 port on the Dell G5, also connect the DP cable from the GPU to my ultrawide monitor (LG 34GP950G-B);
3. Turn on the computer, I got a message from the BIOS saying that the connected port is not for power supply (I don't remember exactly the message but I can try to post here later) then I pressed "Continue" and Windows will start and automatically install the components, wait for it.
4. Downloaded the latest graphic drivers via NVIDIA's website (note: GeForce Experience could not found the latest version, always telling that my drivers were up to date, and Nvidia Control panel was not working correctly).
5. After the installation, checked if all the components were installed (recognized by Windows), I also had to disable my dedicated 1660 Ti otherwise in some games it would lag from time to time.
6. Tested it by playing some games, works like a charm! Of course not getting 100% of the power of the RTX 3070 Ti but I am still playing a lot of recent AAA Games with 60+ FPS.

I am happy with this combination, soon I can post some benchmarks here.
I still have to test it with my LG Gram 2020.
